IMPROVEMENT IN IRON ROOFING.

Specification forming part of Letters Patent No. 218,085, dated July 29,1879; application filed April 26, 1879.

To all whom it may concern:

Be it known that I, GRIFFITH B. THOMAS, of Point Pleasant, in the countyof Mason and State of West Virginia, have invented a new and ImprovedIron Roofing, of which the following is a specification.

The object of this invention is to secure the sheets of iron forming theroof in place without the use of nails, rivets, or any similar device.

It consists in forming the joints between the sheets by crimping theedge of one over the turned up edge of the adjoining sheet the wholelength, and then fastening them by clips of tin in a manner that will befully set forth farther on.

In the accompanying drawings, Figure l is a section of the roof, showingthe manner of forming the joint and applying the clips. Fig. 2 is aperspective view of a roof constructed according to my improvement.

Similar letters of reference indicate correspondin g parts.

Referring to the drawings, A A A are the sheets of metal forming theroot. In applying these, the edge a of one is turned up at a rightangle.The edge of the adjoining sheet is likewise turned up at a right angle,and then turned over again,forming a cap, I), the whole length of thesheet, as clearly shown in Fig.2.

One edge of each sheet is thus formed into a cap, while the oppositeedge is turned up to receive the cap of the adjoining sheet, as shown,and at the peak the sheets are joined in the same manner as in Fig. 1.

The joints are fastened by clips B, applied 11 the following manner: Theend of the clip is fastened to the sheathing under the sheet, that has acap, 1), formed on its edge. Thus, in Fig. 1 the end 0 of the clip isfastened to the sheathing with a nail. The clip is then bent up againstthe face of the upturned edge a, and then carried over and downward. Thecap 11 is then placed over the clip and edge a, and the free end at ofthe clip turned up under the edge of the cap, and then carried over thecap, and the end bent down against the side thereof, as clearlyindicated in the drawings, the free end of the clip being designated bythe letter d. I

In this way the edges of the sheets are socurely fastened together, sothat there is no danger of their separating or of the capslifting fromthe upturned edges of the sheets. After the sheets are placed on andfastened in this way, the joints between the caps 11 and edges to may betightened by the tongsin the usual manner.

Having thus described myinvention, Iclaim as new and desire to secure byLetters Patent- In combination with edge a and cap 1), formed by theextended edge of the sheet A, the clips B, one end fastened to thesheathing under the sheet, having cap I), While the otheris carriedunder and over the outside of the cap to fasten it to the edge a, andthus firmly secure the two together in the manner substantially asdescribed.
